Portugal generated more than 70 percent of its electricity from renewable sources of energy during the first quarter of 2013, a record amount fueled largely by hydroelectric and wind energy sources, according to a report from the country’s grid operator. Hydroelectric generation provided 37 percent of the nation’s electricity from January to March, a 312-percent increase compared to last year, while wind energy accounted for 27 percent, a 60-percent increase, Redes Energéticas Nacionais (REN) reported. While favorable weather helped drive the record levels in wind and hydroelectric power, the results also reflect Portugal’s investment in renewable energy projects — including wind farms, hydroelectric, solar and wave energy — and an improved electricity grid that allows green energy providers to connect into the system. Nearly 45 percent of the country’s electricity will come from green sources this year compared with just 17 percent five years ago, ThinkProgress reports. Meanwhile, generation by coal-burning plants and natural gas thermoelectric stations during the first quarter fell by 29 percent and 44 percent, respectively, compared with 2012 numbers, REN reported.
